Making it Work
The device is partially working with recent kernels, but it refuses to tune to any DVB-S2 transponder, locks up your system for some seconds if you are trying to do so and crashes from time to time with usb transport errors.
To make DVB-S2 working, you have to compile the recent drivers from git://linuxtv.org/media_build.git with the following patch: https://patchwork.linuxtv.org/patch/22003/ - the patch has been rejected because of the bad quality, but is currently your only chance to make it working. (and is working fine, at least with my two tuners (Rev. 1 and 2))
If needed, download the firmware for the card: (sudo) wget -O /lib/firmware/dvb-usb-az6027-03.fw https://github.com/OpenELEC/dvb-firmware/raw/master/firmware/dvb-usb-az6027-03.fw
Now the device is working, but it is crashing every now and again, locking up the whole usb subsystem, especially if you have a Rev. 1 tuner.
To fix this, add the following line to /etc/udev/rules.d/99-local.rules:
ACTION=="add", SUBSYSTEM=="usb", ATTR{product}=="SkyStar 2 HD CI", ATTR{power/control}="on"
This will stop the device from going into powersave mode, which seems quite unstable.
After a reboot, everything should be working fine.
